Your baby is learning and growing by leaps and bounds now! In the coming weeks, he'll likely say consonants, such as t or d, or a consonant-vowel combo like "ta" or "da." In the coming weeks, your baby will begin to sit up unassisted. He also can put his hands together, grasp an object by raking his fingers across it and move objects from hand to hand.
Rolling over used to be a 4-month milestone, but now it is happening later, at around 5 months. Put your baby on his stomach for at least a half-hour a day to build upper-body strength. Now is also a good time to begin playing simple sound-gesture games, such as "Where is Thumbkin?" and "Itsy Bitsy Spider." Your baby may begin to make trilling, growling and lip-smacking sounds.
By 3 months, your baby can grasp a rattle that's placed in his hand and bring his fingers into his mouth. He also can lift his head 45 degrees while lying on his tummy and can push his legs down when held standing. If your baby does not smile socially, coo or lift his head 45 degrees at 3 months, talk with your pediatrician.
